In the interests of having a TED that works on both my systems I am looking to trade my working v2.2 for a working v1.2.
The Turbo Everdrive V2.2 works fine with the Duo (Turbo Duo, PCE Duo, Duo-R/RX) systems, but is not a good candidate for US TG16's. It's also not good with Core units since they only work reliably without anything attached to them (i.e. Tennokoe Bank & CD-ROM2).
If you only own a Duo console and never plan to buy anything else, this is a good opportunity to swap for a unit with faster (near instant) rom loading.
My memory card slot has no trouble clearing the power switch on my TG-16 or Duo. Some people have reported problems but I have had no such problems, at least with the memory cards I've tried. My unit is working consistently with my Duo but is a no-go with my TG-16.
I still have the original box it came in. It is a bare PCB with no 3D printed cover. I'm in Canada but willing to trade with people in the US as well.
